Key Benefits & Features

  • Designed for continuous 24/7 operation in demanding applications
  • Compact, all-in-one structure saves time and space
  • Easy installation on all hydraulic systems
  • Utilizes machine’s or vehicles engine as a power source via hydraulics – no separate engine to maintain
  • Low maintenance, reliable, and always ready for use
  • Produces compressed air at pressures of up to 15 bars
  • Outputs from 500 l/min (17.7 CFM) to 11,000 l/min (388 CFM)

How Does the Hydraulic Screw Compressor Work?

The hydraulic compressor utilizes a machine’s, vehicle’s, or vessel’s hydraulic system as its power source to produce airflow.

  • Hydraulic oil flows to the hydraulic compressor’s integrated hydraulic motor through the pressure line.
  • The hydraulic compressor converts hydraulic oil flow and pressure into compressed air.
  • The hydraulic oil is returned to the carrier machine’s hydraulic oil tank via the return line.
  • The screw compressor is equipped with an oil heat exchanger that transfers heat to the carrier machine’s hydraulic system for cooling.
  • The hydraulic screw compressor can operate continuously 24/7 without stopping. It runs at idle speed when not producing airflow.
